Holy crap, you are a fourth dan in Tang soo do, I practised Tang soo do for around 2 years, until my mother had some disputes over the financial arrangements with our instructor Louis Soma...maybe youve heard of him, and I had to drop out. I have not heard of him, but there are several different Tang Soo Do organizations. I belong to the World Moo Duk Kwan Tang Soo Do Federation. Do you remember which organization did you belong too?
